I am usually the only driver, no one else in the car. 04 highlander.
is it posible to buy a seat cover of some type for just the drivers seat?
the areas where you slide into the car are beginning to wear.
seems there would be a big demand.
some on internet look too cheap, some too expensive
Prius? In line water heater? Solar?
All save energy, but may not save money (complicated, no DIY, parts hard to get, , parts expensive, etc).
